Previously, one would check the value in &confInt["someKey"] by passing a reference to it to evalIntConf. However, because this passing of the reference went through std::unordered_map::operator[], it created a slot with the named key and initialised its value with the default constructor of int, which placed 0 there, if it didn't exist. If the value of 0 was acceptable for the setting, then 0 as the value selected by the user was indistinguishable from a slot that had been just created and had to be set to its default. Now, the std::unordered_map is passed along with the key so that evalIntConf can check whether the key exists and, if it doesn't exist, set the value to its default. Include utilities.h in gmenu2x.h instead of the reverse. One type definition used by utilities.cpp is moved there (ConfIntHash) and for consistency ConfStrHash is moved there as well.
